  Ionisers in air purifiers are often marketed as a bonus feature, but they mostly boost lab test numbers rather than actually cleaning your air. Ionisers charge particles so they stick to surfaces instead of being trapped in a HEPA filter. They can artificially increase CADR scores, and turning them off usually means lower real-world performance. A test on a Blueair unit found 20–50% of CADR came from the ioniser, not the filter. Ionisers can create ozone and chemical byproducts, and increase visible dust on surfaces. HEPA-only purifiers with decent airflow are simpler, safer and more transparent. 1. The benefits ionisers claim to offer Manufacturers usually claim ionisers: “Freshen the air” “Neutralise pollutants” “Boost cleaning efficiency” “Tackle ultra-fine particles too small for filters” “Break down odours and VOCs” On paper it sounds impressive. In reality: Ionisers don’t capture particles, they just charge them so they fall onto surfaces. They don’t improve actual filtration. And the air isn’t cleaner, your surfaces just get dustier. What ionisers actually do is charge particles in the air so they stick to nearby surfaces (walls, furniture, your lungs, your skin) instead of staying airborne. 2. How ionisers inflate CADR scores without really cleaning the air This is a key reason manufacturers love ionisers. CADR tests (Clean Air Delivery Rate) measure how fast particle levels drop in a sealed test chamber. The test doesn’t care whether those particles were: Actually filtered through a HEPA filter, or Simply knocked out of the air and stuck to surfaces by the ioniser Ionisers make particles drop faster, so the CADR number gets a boost - even though the purifier hasn’t genuinely “cleaned” more air. 🚨 Important:Most purifiers let you switch off the ioniser, but when you do, the CADR is often much lower than advertised. Manufacturers almost never publish the “ioniser off” CADR, so consumers are left thinking they’re buying a higher-performing unit than they actually are. A third-party test of a Blueair purifier shows how big this gap can be. With the ioniser turned off, CADR dropped dramatically across particle sizes. Smoke fell by 44%, dust by 19%, and pollen by 53%. The researchers concluded that around 20–50% of the purifier’s measured CADR came from the ioniser, not the actual filter. Read the full report here This is why brands love ionisers: Very low manufacturing cost Bumps the test numbers Helps justify a higher price No obligation to reveal the real, filter-only performance 3. A very cheap add-on that creates a higher-priced product Ioniser modules cost very little to manufacture. Far less than a better motor, fan, or filter. But because they artificially boost test numbers, brands often use them to justify: Bigger “high-performance” claims A higher RRP Positioning the unit as “premium” or “advanced” It’s a low-cost trick with a high-margin payoff. This is one reason so many mass-market purifiers include ionisers by default: not because they’re effective, but because they sound impressive and help the spec sheet stand out. 4. The word ‘ioniser’ often goes by different names Because many people are wary of ionisers (especially due to ozone concerns), companies often rebrand them under different names, including: “Plasma ion technology” “Plasmacluster” / “PlasmaWave” “Negative ion generator” “Cold plasma” “Hypoallergenic mode” “Nanoe” “Streamer" Different name, same mechanism: charging particles so they stick to surfaces. If a purifier advertises “ionic”, “plasma”, or “active air cleaning”, always double-check what it actually does. 5. They can increase visible dust, not reduce it Because ionisers push particles out of the air and onto surfaces, you often end up with: More dust settling on furniture Black streaking on walls (common with bipolar/“plasma” units overseas) Dust build-up inside the purifier housing A proper HEPA purifier captures dust inside the filter and removes it from circulation entirely. 6. Health side: ozone, byproducts, and why NZ schools were told to avoid ionisers Ionisers can generate small amounts of ozone as a by-product. Even when the levels are low, ozone is a highly reactive gas. Indoors, it can react with everyday chemicals, things like cleaning products, perfumes, building materials and even the natural oils on skin and surfaces to create new VOCs and aldehydes. So instead of reducing chemical pollution, ionisers can unintentionally add extra byproducts to your indoor air. This is one reason many public health and education bodies advise against ionisation devices. In New Zealand, the Ministry of Education’s official ventilation guidance was very clear by requesting schools do not purchase air purifiers with ionisers for classrooms. “We recommend air cleaners with high-efficiency HEPA filters, and do not use emerging technologies that emit any substances into the air (for example ionisers, plasma discharge, ozone generators, photocatalytic oxidation or hydrogen peroxide).” That’s a strong signal that ionisers and other “active” purifier technologies aren’t yet considered safe or reliable in real-world indoor environments. 7. So why doesn’t Snap Air sell ioniser purifiers? Because they don’t fit what we stand for: No gimmicks to inflate CADR No cheap “add-on” used to justify a higher price No hidden chemistry that could add byproducts to your air All the purifiers we sell stick to transparent, well-understood tech: High airflow Proper HEPA filters Carbon filters where odours/VOCs genuinely need to be reduced No ionisers, no plasma marketing, no mystery “active” systems When you see a CADR figure on our site, it’s coming from actual filtered airflow, not ions knocking particles onto your walls. 8. What to look for instead of ionisers If you’re shopping around and want genuinely cleaner air, focus on: HEPA filter: H12 or H13 for particles CADR / airflow: big enough for your room size and target air changes per hour Carbon filter: only if you need help with smells or VOCs Noise levels: so you can actually run it at an effective speed Honest specs: no vague “plasma”, “ionic shield” or “active molecular” language You don’t need fancy-sounding tech to get clean air. You just need: A decent fan + a good HEPA filter + enough airflow for your space. If you want to skip the ioniser maze, every purifier we stock is ioniser-free and HEPA-based only, so the performance you see on the spec sheet is what you actually get in your room.

Dust is one of those things every home has, and no air purifier can make it magically disappear. But a good purifier can make a noticeable difference - as long as expectations are realistic and you choose the right machine. Here’s a clearer look at how dust actually works, and what an air purifier helps with. Dust isn’t just one thing Dust is a mix of all sorts of stuff: dead skin cells, fibres, soil, pollen and plenty more. Importantly, most of the dust you actually see tends to be the heavier bits. This is the kind that settle quickly on shelves, floors and TV stands. Meanwhile, the smaller, lighter particles (the PM2.5 type) stay airborne longer. These are the ones commonly linked to allergies and respiratory issues, and they’re exactly what HEPA purifiers are designed to capture. So… can an air purifier get rid of dust? Yes - but only the dust that reaches it. If dust is floating in the air long enough to be drawn into the purifier, it’ll be captured by the HEPA filter. That part works extremely well. But visible dust that has already settled? That’s where expectations need to be realistic. Air purifiers don’t vacuum floors or wipe surfaces. The heavier particles simply don’t stay airborne long enough to make their way into the purifier before they fall. You’ll still need to dust, but usually less often Many people find that while a purifier won’t eliminate visible dust, it can slow down how quickly surfaces get dusty, especially if: It runs continuously You run it on a higher speed when cleaning or vacuuming (which kicks particles into the air) The purifier has a high CADR (Clean Air Delivery Rate) A higher CADR simply means the purifier moves more air through the filter each minute, so it has a better chance of catching particles before they settle. What about ionisers and “negative ions”? You’ll see many purifiers advertise ionisers or “negative ion” features. While they can make particles clump together, this often leads to more dust settling on surfaces, not less. They don’t actually remove the dust from your home, they just make it fall out of the air faster. They also don’t replace a proper HEPA filter, which is what actually captures particles. For most people, especially those dealing with allergies or wanting less dust in the air, a HEPA-based purifier (without ionisers) is the better choice. It cleans the air without creating extra surface dust or producing ozone. HEPA filters catch the fine stuff extremely well The main win with a purifier isn’t reducing visible dust - it’s reducing the fine, invisible particles that you breathe in. These are the ones that can cause irritation, asthma symptoms and allergies. If fine dust is the issue (particularly PM2.5), you’ll get a very noticeable difference with a properly sized purifier. What about “dusty rooms” or homes that get dusty very fast? A purifier can help, but it won't fix the root cause. Common sources include: Open windows on windy days Construction or farm activity nearby Indoor renovations Leaks in older homes Dust blown from heat pumps or ventilation systems Carpet shedding A purifier improves what’s airborne, but it can’t stop dust being created or stirred up. The bottom line A good HEPA air purifier won’t eliminate dust, and it’s better to be upfront about that. What it will do is: Capture fine particles extremely effectively Reduce how much dust stays airborne Slow down how quickly surfaces get dusty (in most cases) Significantly improve overall air quality If you’re choosing a purifier specifically for dust, the most important spec to look at is CADR. A higher CADR means more airflow, and more airflow means more chances to catch those particles before they settle. And of course, if dust is bothering you, a quick vacuuming session right before switching the purifier to a higher speed can help it grab more of the stuff that gets kicked into the air.

If you've been searching for Air Purifiers recently on Google here in New Zealand, you may have come across ads identifying the "Top 5 Air Purifiers in NZ" or "Top 5 Air Purifiers for Allergies in NZ" looking something like this: Who's running this campaign? Quickly, we notice it's from brands we've never heard of here, Hotselects and Trustyrates? Well, that's because it's an ad campaign run by a company in China, funneling people to buy their unknown air purifier: Attempting to Sound Credible If you go onto the websites, at first glance it appears legit. Run by someone called 'Evan Mitchell' who is apparently a seasoned air purifier reviewer. However a quick google turns up no information on him, and the picture looks AI generated. It's also a little strange he runs both websites, and his email address is matt@trustrates.com for one of them! The descriptions are also very clearly AI generated:   Now onto the content. It does include useful pointers on what to look for (HEPA filters, high CADR and avoiding ionisers. Okay, all fine with us - we'd agree these are all useful things for people to know when choosing an air purifier. Now, who's the Surprise Winner? Funny enough, the number one rated purifier on each site is one we've never heard of before! They aim to make it sound more legit by including comparisons to other well-known products such as the Dyson TP09 or the Levoit 600S. You can clearly tell it's designed to promote one specific product, as the winner is also the only one with a link to view the product! Hotselects Winner: Marvics Air Purifier Well, a very clear winner here. So many pros, and the only cons being that it's online only and frequently sold out due to high demand! Although it's not lost on us that it shows a Pro as being negative ion generation, yet just above it says to avoid ionisers. Almost sounds too good to be true... Trustrates Winner: GLO Air Purifier Another one we've never heard of. It includes all the same features and pros as the Marvics purifier, the same cons! Even the same picture... Let's take a look at the product Conveniently the Marvics is on sale for only $309, saving $260! Lucky we got in now before the sale ends in less than 10 hours. Although, when I looked a few weeks ago there was the exact same sale - must have been a coincidence. 7743 sold in total and only 3 left, boy they're putting the pressure on for you to buy now! They've hit all the classic sales and trust cues. Raving reviews from Consumer Reports, CNET, Wired, Fox News. Heck, even the Cambridge Dictionary has reviewed them - must be really something special! Even more amazing, given it has a quoted Clean Air Delivery Rate (CADR) of 80m³/hour, which is one of the lowest of any purifier you can find. Of course, if you try google these reviews you'll turn up a blank. Because Marvics/Glo has no presence anywhere else. It only exists in this eco-system, built by AI to funnel people to a seriously overpriced air purifier. Looks like they're doing this around the world, as their Trust Pilot page shows quite a few very unhappy customers...

This is our third year running this nationwide comparison, now updated for 2025. Over that time, we’ve seen plenty of air purifiers come and go - often from brands where air quality isn’t their main focus. Some even vanish entirely, leaving users without replacement filters. That’s why we refresh this guide each year: to show which models are properly supported in New Zealand, how they actually perform, and which ones deliver the best value for clean air. 1. How We Compare Purifiers We focus on the two figures that matter most: Clean Air Delivery Rate (CADR) and noise (dB). 💨CADR measures how much clean air a purifier produces each hour. The higher the number, the faster it cleans and the larger the space it can handle. We use this figure because manufacturer recommended room sizes are often inaccurate. 🎶Noise tells you how comfortable it is to live with. We use maximum noise levels for fair comparison, rather than the quiet “sleep-mode” numbers that hide reduced airflow. As a guide: <50 dB - relatively quiet for daytime use, fine in living areas but still very noticeable at night 50–54 dB - modest background noise, upper limit for comfortable indoor environments 55–59 dB - similar to normal conversation, very noticeable if close by 60+ dB - loud and disruptive, best avoided for long periods Together, these two metrics give the clearest picture of real-world performance: how quickly a purifier cleans the air and how comfortably it does it. 2. Comparison Analysis (2025): Our latest update shows a clear pattern: price doesn’t always equal performance.Some premium models look impressive but move surprisingly little air, while several affordable purifiers outperform nearly everything in their range. Let’s start with the best air purifiers under $300 - where quiet, efficient performance matters. 3. Budget Air Purifiers Under $300 (for smaller spaces, up to ~40m²) This category is aimed at bedrooms, nurseries, and smaller living areas/apartments. This is for those wanting quiet, effective air cleaning without spending a fortune. We assessed 12 models from brands such as Breathing Better, Sunbeam, Breville, TruSens and more. 🏆 Best Overall: Smart Air Sqair 📊 Key Stats: CADR: 315 m³/h (>50% higher than competitors) Noise: 23–52dB (on low, whisper-quiet) Room coverage: Cleans a 43 m² room in just 20 minutes Price: $299.99 👍 Why we like it: The Sqair delivers the most clean air for your dollar - more than any purifier under $300 in New Zealand. Its H12 HEPA filter has a large 1.5 m² surface area (around 22 A4 pages), giving excellent capture efficiency for smoke, dust, pollen, and pet dander. It’s also 7–12dB quieter than its nearest rivals, making it ideal for bedrooms or nurseries where silence matters. And because it relies purely on proven HEPA + Carbon filtration (no ionisers, no ozone), it’s a safe, science-based choice for households with respiratory concerns or young children. 🔍 How It Compares Brand Model Max CADR  Max Noise Price Smart Air The Sqair 315m³/hr 52dB $299.99 Sunbeam Fresh Protect* 193m³/hr* 59dB $248.00 Trusens Z2000 190m³/hr 64dB $229.00 Breville The Easy Connect 91m³/hr 60dB $270.00 * This purifier includes an ioniser/plasma function. We generally recommend turning ionisers off, as they can produce unwanted byproducts - but switching them off may also reduce the purifier’s CADR, sometimes by a large margin. If you want a clear breakdown of how ionisers work (and why some brands use them), see our full guide → Despite being similarly priced, most competitors clean 40–60 % less air and run significantly louder. The Sqair comfortably handles rooms up to 43 m², reaching that target in just 20 minutes - while others in this range top out around 26 m².  It’s a clear reminder that price doesn’t always equal performance. Graph 1: Air purifiers under $300 in NZ (price vs max noise vs CADR). 4. Air Purifiers $300 to $500 in New Zealand (for medium spaces, up to ~60m²) This range suits medium-sized living rooms, apartments, and shared spaces where you want strong air cleaning without excess noise. We compared 14 models from brands like Daikin, Shark, Winix, Breville, Xiaomi, TruSens and more. 🏆 Best Overall: Smart Air SA600 📊 Key Stats: CADR: 500 m³/h, equal to the highest in this bracket Room coverage: Cleans a 60 m² room in just 18 minutes Noise: 16 – 51dB (quietest in class) Price: $439.99 👍 Why we like it: The Smart Air SA600 packs big-room performance into a compact, low-noise design. Its dual-inlet setup and twin H13 HEPA + carbon filters deliver clean air more efficiently than purifiers twice its price. It matches the top CADR of the Xiaomi Pro 4 but runs up to 13dB quieter, making it much more comfortable for everyday use. Unlike many competitors that rely on ionisers or plasma features, the SA600 uses straightforward science. That's a powerful fan and real filters for reliable, safe air cleaning. Add its “Do Not Disturb” mode to avoid lights and child lock, and you get a purifier built for homes, offices and schools alike. 🔍 How It Compares Brand Model Max CADR  Max Noise Price Smart Air SA600 500m³/hr 51dB $439.99 Xiaomi Pro 4 Smart Air* 500m³/hr* 64dB $400.00 Xiaomi 4 Smart Air* 400m³/hr* 63dB $325.00 Shark NeverChage 5 165m³/hr 55dB $350.00 * This purifier includes an ioniser/plasma function. We generally recommend turning ionisers off, as they can produce unwanted byproducts - but switching them off may also reduce the purifier’s CADR, sometimes by a large margin. If you want a clear breakdown of how ionisers work (and why some brands use them), see our full guide → The SA600 offers a rare balance of high airflow and low noise, outperforming most competitors in both areas. It delivers top-tier cleaning power while remaining comfortable to live or work beside, even on full speed. By contrast, the Shark NeverChange 5 is heavily marketed, but falls short in performance. With a CADR of just ~165 m³/h, it moves a third of the clean air of the SA600, yet operates at 55dB or more. The SA600 achieves almost the same airflow at only 16dB on low speed, virtually silent! It’s a clear example of why transparent CADR data matters more than marketing labels, and why the SA600 stands out as the most capable and honest performer under $500. Graph 2: Air Purifiers $300- $500 in NZ (Price vs max noise vs CADR). 5. Air Purifiers for larger spaces under $1000 in New Zealand (Up to ~85m²) When you’re dealing with large living areas, classrooms, clinics, or open-plan apartments, you need serious airflow without the jet-engine noise. We assessed 15 models in 2025 from brands like Sharp, Daikin, Oransi, Winix, Mitsubishi, Breville and Dyson. Performance varied dramatically - some delivered genuine whole-room cleaning, others struggled despite premium pricing. 🏆 Best Overall: Smart Air Blast Mini Mk II 📊 Key Stats: CADR: 740 m³/h highest in its class Room coverage: Cleans 85 m² in just 17 minutes Noise: 49dB max, quietest among large-space units Price: $799.99 👍 Why we like it: The Blast Mini Mk II is built for genuinely big rooms. Its massive airflow and large H13 HEPA + optional carbon filter give it the power to handle living rooms, classrooms, or open offices with ease, all while staying impressively quiet. At just 49dB on high, it’s quieter than many smaller purifiers running on medium. Smart Air’s “fan + filter, no gimmicks” approach means there are no ionisers, plasma emitters, or inflated “air quality modes” - just straightforward, high-volume HEPA filtration that works. 🔍 How It Compares Brand Model Max CADR  Max Noise Price Smart Air Blast Mini Mk II 740m³/hr 49dB $799.99 Oransi Mod Hepa 574m³/hr 49dB $850.00 Mitsubishi ElitePure 508m³/hr 55dB $520.00 Dyson Pure Hot+Cool HP03 113m³/hr 62dB $899.00 The Blast Mini Mk II delivers both the highest CADR and lowest noise in its category, making it a standout for large spaces. The Oransi Mod HEPA is a solid performer but still trails well behind in airflow. Meanwhile, Mitsubishi’s ElitePure offers less than 70 % of the Blast Mini’s output, and Dyson’s HP03 barely registers for its price tag. Dyson’s independently tested CADR of just 113 m³/h, and at a noisy 62dB, shows how marketing can mask poor real-world performance. The Blast Mini, by contrast, backs its claims with transparent data and measurable results. Graph 3: Air purifiers $500 - $999 in New Zealand (price vs max noise vs CADR). 6. Large & Commercial Air Purifiers over $1000 in New Zealand (Up to ~130m²) This category covers large homes, gyms, clinics, classrooms, and shared spaces - anywhere serious clean-air output is needed. We tested 15 models from brands such as IQAir, Trusens, Dyson, Breathing Better and Fellowes. Prices vary widely, and as with smaller categories, cost doesn’t always equal performance or quietness. 🏆 Best Overall: Smart Air Blast Mk II 📊 Key Stats: CADR: 950 m³/h, highest in New Zealand Room coverage: Cleans 130 m² in 21 minutes Noise: Just 43 dB, the quietest large unit around Price: $1,100 👍 Why we like it: The Blast Mk II delivers industrial-level performance in a package that’s surprisingly quiet.At 950 m³/h CADR, it outperforms or matches high-end purifiers costing several times more - while running at only 43 dB, about the sound of a quiet conversation. It’s built around Smart Air’s no-nonsense principle: massive HEPA surface area, high airflow, and zero gimmicks With H13 HEPA and optional carbon filtration, it’s ideal for schools, fitness studios, or any environment where dependable, high-volume clean air is needed without the distraction of fan noise. 🔍 How It Compares Brand Model Max CADR  Max Noise Price Smart Air Blast Mk II 950m³/hr 43dB $1100 Trusens Z7000 930m³/hr 66dB $1830 Trusens Z6000 880m³/hr 63dB $1700 IQAir CleanZone SL 820m³/hr 56dB $11,500 Breathing Better* X-Large Room Purifier* 800m³/hr 70dB $1499 I-Air Pro Air Healer 600m³/hr 61dB $12,883 Dyson Purifier Hot + Cool 311m³/hr 62dB $1099 * This purifier includes an ioniser/plasma function. We generally recommend turning ionisers off, as they can produce unwanted byproducts - but switching them off may also reduce the purifier’s CADR, sometimes by a large margin. If you want a clear breakdown of how ionisers work (and why some brands use them), see our full guide → The Smart Air Blast Mk II pairs immense airflow with unmatched quietness, achieving what most large-space purifiers can’t: power and comfort in the same package. The Trusens Z7000 comes close in airflow but runs over 20 dB louder, while the IQAir focuses on the high end with specialised carbon filtration and an big price tags. At the opposite end, Dyson’s premium Hot + Cool series delivers less than a third of the airflow at very high noise levels - proof that sleek design doesn’t equal clean air. Graph 4: Air Purifiers $1000+ in New Zealand (price vs max noise vs CADR). 7. Summary: What We Learned From the Comparisons After analysing nearly every purifier available in New Zealand, one trend is clear: the best-performing units aren’t always the most expensive. Across all categories, CADR and noise tell the real story. Some premium models look sleek but move little air, while smaller specialist brands often deliver far higher performance for their price. The purifiers that consistently stand out combine: High CADR – lots of clean air, fast Low noise – quiet enough for daily use Reliable filter support – parts readily available in NZ 8. How We Source and Verify the Data We’ve made every effort to ensure the numbers here are accurate and up to date, but air purifier data can be patchy. Some brands don’t publish CADR or noise levels at all (we’re looking at you Dyson and Shark), or publish only partial figures. Here’s the approach we use, for all purifiers we find available in New Zealand: Manufacturer or retailer specs - when CADR and noise levels are published clearly. EnergyStar database - where CADR is independently verified. Independent tester reviews (e.g. Housefresh, Rtings) when official data isn’t available. If no reliable CADR data can be found, we exclude the model. That’s why this guide shows every purifier in NZ with verifiable performance data. While we’ve double-checked everything, there may still be small differences between sources. 9. Why Can You Trust This guide? The internet is full of “Top 10 Air Purifiers” and “Best Purifiers for Dust” lists - even from well-known outlets. Unfortunately, many are built to generate commission, not to give you the best advice. We want to be upfront: yes, we are selling some of the purifiers in this guide. But unlike affiliate-driven lists, our business depends on you being satisfied years down the track. That means filters being available, performance matching the claims, and you getting genuine value. That's why we aren't just telling you which are the best, we're showing you the data so you can make an informed decision. 10. Why you can’t trust every “Best Of” list To show what we mean: in 2024, the NZ Herald published their “Best Air Purifiers in New Zealand” picks. The problems? Many. It was clear this was written by someone (or AI) with no knowledge of air purifiers. They included models with poor clean air performance, no filters available and unsupported models drop shipped from overseas. Their reason for publishing isn’t to inform you, it’s to earn commission on the products they list. We broke this down in detail here: It's a good reminder that while these lists look authoritative, they don't hold up when you check the numbers. Our aim is different: to compare all models where data exists, show how they stack up, and make it transparent why certain units come out ahead. 11. Features That Don't Add Real Value When shopping around you’ll see lots of air purifiers with added bells and whistles. Some of these aren’t just unnecessary, they can be unhelpful or even harmful: Ionisers / Negative ion generators - can create ozone and just push particles onto surfaces instead of removing them. These are used to improve CADR figures, without filtering out particulates. UV lights - sound impressive, but don’t get enough contact time to work in fast-moving air. HEPA filters already capture these particles. Auto sensors - often cheap, inaccurate and misleading. We recommend a separate, accurate monitor if you want to track your indoor air properly. 👉 For a full breakdown, see our article: What features matter when choosing an air purifier. 12. Final Thoughts This guide compares nearly every purifier currently sold in New Zealand, from compact bedroom models to large commercial systems. Whatever your space, the same principles apply: Focus on CADR and noise, not gimmicks Make sure filters are available locally Choose a model that matches your room size and how you’ll use it 👉 Still not sure which model fits your space?

It's hard to beat the aroma of garlic or steak sizzling away on the frypan as it fills your kitchen with flavour. But under those delicious scents lies fine particles called PM2.5, that can travel deep into your lungs and affect your indoor air quality. In a test in a Christchurch apartment in May 2025, cooking on a front burner pushed PM2.5 levels throughout the apartment into the hazardous range, even with the rangehood set to full power. In this article we'll show you exactly how we measured those spikes, how bad it got and how much of a difference using Air Purifiers made. Armed with this information, you can ensure you keep your air clean, whatever you're cooking! Figure 1: Rough Layout of Apartment + Positions of Monitors and Purifiers First Test: Baseline (No Air Cleaning) This experiment actually started accidentally, after noticing the air quality as measured on my QP Pro units was at very concerning levels. It turned out that even at full power, my rangehood barely captured smoke from the front two hobs. This is definitely a bit of a surprise given this is a relatively new apartment.After frying for about 15 minutes, it seemed a little hazy and smokey inside. I checked my air quality monitors in both the lounge and separate bedroom, and both showed very high readings! With PM2.5 counts of over 300 µg/m³, you really want to limit your exposure to this. For perspective, this is about three times higher than the average pollution level in Delhi, and is well into 'hazardous' air quality levels.  If you stop cooking, you immediately remove the PM2.5 source. But on a chilly day with windows closed, those particles can linger for hours. While the rangehood extractor fan was used, it hadn't effectively drawn out the cooking smoke. Being a chilly day, no windows or doors were opened. Here is how the air quality looked over the evening: Figure 2: PM2.5 Readings in Bedroom and Lounge from Cooking Note: PM2.5 to air quality ratings sourced from EPA AQI breakpoints. As you can see, the PM2.5 levels shot up very quickly when the cooking started. For several hours the air quality was at or above unhealthy levels, even lingering at hazardous amounts for awhile! What does this mean? Basically the equivalent of smoking about 1.3 cigarettes! Definitely not something you want to be regularly exposed to. Especially if you have asthma or other breathing sensitivities. Second Test: With Air Purifiers This time, our accidental experiment was repeated with one key tweak, switching on air purifiers when the concentrations peaked. The apartment is well covered on that front, with a Smart Air Sqair in the bedroom and a Smart Air SA600 in the main living/kitchen area.You'll notice from the layout graphic earlier, we've also placed the purifiers away from the air quality monitors. This helps ensure the readings are representative of the actual air quality in the apartment, and not just the air quality around the purifier.Now the big reveal, how much of a difference can the air purifiers make? We allowed the PM2.5 concentrations to reach similar levels to our baseline test, and then turned both purifiers on at their max power settings. Figure 3: PM2.5 Readings in Bedroom and Lounge from Cooking, using Air Purifiers The outcome? In just 30mins, PM2.5 concentrations had dropped by over 90% - this is compared to between 25% and 29% when we didn't use them. Air quality reached the optimal 'Good' level within 45mins in the bedroom and within 1 hour in the main living area!Why are these air purifiers so effective at removing cooking pollutants and smoke? It's all thanks to the combination of HEPA filters and high Clean Air Delivery Rate (CADR).  The HEPA filters on both units are very effective at absorbing harmful particulate matter in the air, such as from frying and smoke. However, a good HEPA filter won't do much if the purifier isn't able to send much air through it. With CADRs of 315m³/hr and 500m³/hr respectively, the Sqair and SA600 are able to push significant amounts of polluted air through their filters. This makes them best in class when it comes to how effectively they purify air. As you can see, we can back this claim up with real data! Smart Air Sqair Smart Air SA600 Stylish, powerful and quiet at a great price. Perfect for the bedroom, or any space up to 43m². Dual inlets with filters on each side. Serious cleaning power for larger spaces up to 60m², while remaining quiet. Other air quality measures you can take: Ensuring your rangehood is working effectively will certainly help reduce the amount of PM2.5 in the air. Mechanical ventilation i.e. HRV/DVS etc if you have it. This will bring in air from outside or the roof space which should be much less polluted. Finally opening windows and doors to let a breeze through, even if for just a short while will also quickly help lower the amount of pollutants.

Like many Kiwis, I used to never give a second thought to the air I'm breathing. Our landscape isn't covered in polluting factories or coal plants and we're known for our (relative) clean air. However, after learning more about indoor air quality, I decided to start monitoring the air inside and was surprised by what I discovered! How do you Monitor the Air? While it's not an uncommon thing to do overseas, monitoring air quality is still something not many Kiwis are familiar with. While it's possible to pay professionals to come in and do a detailed report, there is a much easier (and cheaper) way. Enter the Indoor Air Quality Monitor, a device with sensors to measure air quality issues such as PM2.5, CO2, VOCs and more. For the past 2 years I've used a QP Lite, QP Pro and Smart Air CO2 Monitor to keep tabs on the air in my home. With an affordable price, high accuracy and data download ability, they're some of the best options on the market and we're pleased to stock them here at Snap Air. First Surprise: CO2 Levels While Sleeping Like many of us, I took it for granted that sometimes we'll wake up feeling groggy, tired and maybe with a bit of a headache. While there are many possible causes for this, have you ever considered CO2 might be behind it? Bedrooms are small spaces and if you close the door and windows, where does fresh air come from? As we breathe oxygen is converted to CO2 and without ventilation the levels can rise surprisingly fast! Especially if you have a partner in the same bedroom. CO2 levels are reported in parts per million, with outdoor air being around 420ppm. Once the air reaches 1000-2000ppm you'll typically experience drowsiness and from 2000-5000ppm headaches and other complaints can occur. I was very surprised to see the levels for my bedroom at night regularly reach over 3000ppm! Once I improved the ventilation, I noticed I'd wake up feeling less groggy and more alert.  Below is an example comparing relatively good ventilation in a bedroom (initially) then poor ventilation later in the week. You can also see just how quickly the CO2 levels drop when ventilation is introduced (opening the door) in the morning! CO2 Concentration Levels: Measured with Smart Air CO2 Monitor Second Surprise: VOC Levels in a New Apartment Having moved into a newly built apartment for a period of time in 2023, I found the 'new building smell' very powerful and I would often get headaches. Unfortunately this is a common experience for many new home owners, as the off gassing from paint, flooring and fabrics etc. produces VOCs like Formaldehyde and Benzene. These can cause symptoms like headaches, respiratory issues, dizziness and throat irritations. There was a sharp increase in average VOC levels reported on my QP Pro after moving into the apartment, compared to an older existing house.  Previously, measurements were around 0.3-0.4 mg of TVOC per m³. In the new building, it was 10 times higher and would be between 3 and 4mg per m³. This puts it in the potentially dangerous threshold. Luckily there is action that can be taken to help reduce these levels. The most effective measure is introducing fresh air by opening doors and/or windows. You can also achieve this with mechanical ventilation. If neither of these options are possible, consider an Air Purifier with Activated Carbon Filter. Here are some readings from the apartment showing the slow rise of VOC levels, then how quickly they get eliminated by opening windows and allowing a breeze through! TVOC Concentrations: Measured by QP Pro Air Quality Monitor Third Surprise: PM2.5 Levels from Vaping While there has been a surge in vaping in recent years, we're still learning about its potential impacts. Having lived with someone who vapes in their room, I've been able to see how it impacts on air quality - especially when ventilation is limited. While it produces a fine mist and sends chemicals into the air, the process of vaporising the liquid also sends particulate matter into the air, including harmful PM2.5. To learn more about PM2.5, see the below video: While I wasn't surprised to see vaping having an impact on air quality, I was surprised at just how high the PM2.5 levels would get - even while in a different room. We've had reports from some of our customers about being impacted by others in their household vaping, which isn't surprising given these results! On the plus side, levels do drop fairly quickly back to normal once the vaping stops. However, peak concentrations ended up at levels you'd see in the most polluted cities in the world, at their absolute worst! The below graph shows the levels of PM2.5 measured from an adjacent room to the one being vaped in. PM2.5 Levels: Measured with QP Pro Air Quality Monitor: Wrapping Up Ready to make your own discoveries in air quality? We've got you covered with accurate and affordable air quality monitors! Feel free to leave a comment below if you found anything interesting when you started monitoring your air!

Whether it's moving into a new home or doing some DIY renovations, many of us will be familiar with that 'new home smell'. Unfortunately, behind that smell are a number of potentially dangerous chemicals or VOCs such as formaldehyde! For some this may cause headaches, dizziness and other health issues. This brings us to the question: How do you keep yourself safe from these VOCs and can an air purifier help? The good news is there are ways to mitigate these VOCs and the right air purifier can definitely help! Understanding VOCs and Their Sources VOCs are emitted as gases from certain solids or liquids. Common sources in new builds and renovations include: Formaldehyde: Found in building materials like plywood, particleboard, and adhesives. Benzene: Emitted from paints, glues, and cleaning products. Toluene: Present in paints, paint thinners, and adhesives. Health Impacts Exposure to VOCs can cause, amongst other things: Headaches Dizziness Respiratory issues Eye, nose, and throat irritation Monitoring VOC levels with an Air Quality Monitor Using an air quality monitor with a TVOC sensor, like our QP Pro 2 or the Temtop M10 can help you gauge VOC levels in your home. While you won't see levels of each specific chemicals, measuring the VOCs will help give a picture of baseline levels of VOCs in the air and can show the effectiveness of different tactics in reducing VOCs. Effective Strategies for Reducing VOCs Ventilation The most effective way to reduce VOCs is through ventilation: Mechanical Ventilation: Use exhaust fans or air exchangers like HRV systems. Natural Ventilation: Open windows and doors to create a strong cross breeze. Formaldehyde Cookouts These are a way to force more formaldehyde from building materials, furniture etc. in a shorter period of time. Note you should avoid being inside when the cookout is run. Smart Air have written a detailed guide here, however the basic process is: 1. Close windows/doors and increase temperature, through heating or naturally with sunlight. Aim for 30+ degrees if possible. 2. Keep the temperature up for a few hours, ideally 6-8 if possible. 3. When you return, open windows and doors to remove the formaldehyde from the air and return the space to a normal temperature. 4. Repeat this several times  Air Purifiers with Activated Carbon Filters An air purifier with a carbon (VOC) filter can provide additional assistance, especially when ventilation isn't possible. Key Factors to Consider: Amount of Carbon: This determines the amount of VOCs which can be filtered before the filter becomes saturated. Some mesh-style "carbon filters" may last only a few minutes in high VOC environments. Separate Carbon Filter: Allows for easy replacement when needed, as in high VOC situations the Carbon Filter will likely need replacing well before the HEPA filter. Our Recommended Purifiers: Sqair: 120g of activated carbon per filter. SA600: 140g per filter (2 per purifier). Blast Mini: 650g of activated carbon per filter (optional extra). Blast: 1.06kg of activated carbon per filter (optional extra). For additional VOC cleaning power, you can remove the HEPA filter and use multiple carbon filters in our purifiers.   Wrapping Up VOCs are an unfortunate reality in newly built or renovated homes. It's essential to tackle these to maintain good indoor air quality and health. Ventilation, both mechanical and natural, is the most effective strategy. Additionally, using air purifiers with plenty of activated carbon can provide assistance, especially when ventilation is not possible. Formaldehyde Cookouts are an additional tool to help lower the levels of formaldehyde being released.

In New Zealand, many homes struggle with dampness, especially over the colder winter months. This makes dehumidifiers a common household appliance. As awareness about indoor air quality increases, you might naturally consider an air purifier and dehumidifier combo unit. They promise the benefits of both devices in one, but are they truly effective? This blog explores whether these combo units are worthwhile, especially compared to standalone devices. How Air Purifiers and Dehumidifiers Work Air Purifiers Air purifiers are designed to remove pollutants from the air, including dust, pollen, pet dander, mould spores, and other allergens. They work by drawing air through filters, such as HEPA filters, which trap these particles before releasing the cleaned air back into the room. Dehumidifiers Dehumidifiers, on the other hand, are built to reduce moisture levels in the air. They work by drawing in humid air, cooling it to condense the moisture, and then expelling the drier air. This process helps prevent mould growth and reduces dampness in homes. The Promise of Combo Units The idea behind combo units is appealing: one device that handles both air purification and humidity control. Since both appliances deal with air, combining them seems logical. Why get two separate appliances when they can be combined into one? Different Machinery Requirements However, as you can see from the above images, air purifiers and dehumidifiers require very different internal mechanisms to perform their functions. Combining them into a single unit results in a compromise, where neither function is performed as effectively as in standalone units. Performance in Small Spaces In small spaces like bedrooms or laundries, a combo unit might be passable. However, in larger spaces, the limitations become more apparent. Evaluating Combo Units in NZ We did some research on the available combo models in New Zealand. Note we haven't physically tested these, but rely on the figures provided by the manufacturers. The primary metrics we looked at were CADR (Clean Air Delivery Rate) to assess the air purification ability and the daily moisture removal amounts. As a benchmark for the CADR, 200m³/hour makes it suitable for a space of about 27m². Our base model air purifier, the Sqair has a CADR of 315m³/hour and is available for a price of $299.99. Generally moisture removal levels for standalone dehumidifiers start at about 10L/day for low price models and top out at about 40-50L/day for higher end models. High-End Models Philips Series 5000: Priced around $1200, it offers moisture removal of 25L/day and a CADR of 270m³/hour which is close to our Sqair, but comes at a big price tag to achieve this. Breville Smart Dry 2 in 1: Priced at round $600, it removes 21L/day of moisture and has a CADR of 195m³/hour. This is comparable to the Sqair running on medium speed. Budget Models Unfortunately we're extremely limited in our ability to compare other models we've seen by Sheffield, Dimplex & My Genie. None of these provide any information about CADR, but given their small sizes and low dehumidification performance we can't imagine the CADR is suitable for anything except the very smallest of spaces. However a model shared by Sheffield & My Genie was only able to dehumidify 750mL per day, much much lower than any comparable unit! The Case for Standalone Units Given the high cost of a half-decent combo unit, let's look at why standalone units are the best option for most situations. Efficiency and Performance Standalone air purifiers and dehumidifiers are designed specifically for their respective functions, ensuring optimal performance. A dedicated air purifier will have a higher CADR, and a standalone dehumidifier will remove moisture more effectively. Flexibility Using separate units allows you to address specific needs as they arise. For instance, you can run just the air purifier during pollen season or just the dehumidifier during humid months, saving energy and wear on the devices. You also have significantly more options for features, performance ability etc. Another point is a combo unit means there is one point of failure. For example we've seen reviewers unable to find replacement filters, meaning they can't use the air purifier and they're left with an under-performing dehumidifier. Final Thoughts While air purifier and dehumidifier combo units might seem convenient, they often fall short in performance compared to using separate, dedicated units. If you have space for only one device and are willing to spend a considerable amount, a high-end combo unit might suffice for a small area. However, for most situations, investing in separate air purifier and dehumidifier units will provide better air quality and moisture control. While we don't have recommendations for specific dehumidifiers, if you're looking for great value, quiet and powerful air purifiers then check out our range!

Do air purifiers work for mould allergies? Absolutely, air purifiers with HEPA filters can be a game-changer for those with mould allergies. They're great at capturing airborne spores that can trigger allergic reactions. However, it's important to understand that while air purifiers can help manage the allergens in the air, they don't eliminate the source of mould growth. For that, you need to tackle the dampness and humidity that mould thrives on – and a dehumidifier can be instrumental in this battle. Key Points Summary Air purifiers can help with airborne mould spores, reducing allergens in the environment. They cannot remove existing mould growth, which requires physical cleaning and humidity control. Dehumidifiers are essential in preventing mould by maintaining low humidity. Combined air purifier and dehumidifier units exist but may not be as effective as separate appliances. HEPA filters in air purifiers are effective against mould spores, benefiting those with allergies and asthma. Our range features powerful, affordable air purifiers with HEPA filters, perfect for New Zealand homes. Understanding Mould Allergies and Air Purifiers The Battle Against Airborne Spores Air purifiers are designed to filter out the tiny, airborne adversaries that mould spores can be for many of us. A HEPA filter is particularly effective, capturing particles smaller than 0.01 microns. Much smaller than the typical 3 to 40 micron sizes of mould! When Air Purifiers Meet Mould While air purifiers are perfect for cleaning the air, they can't fight mould growth on surfaces. Regular cleaning and controlling room humidity are essential steps in preventing mould from taking hold in your home. Combating Humidity with Dehumidifiers Dehumidifiers play a pivotal role in mould prevention by maintaining an environment that's inhospitable for mould growth. Keeping indoor humidity below 50% can significantly reduce the risk of mould and keep you comfortable. All-in-One: Solution or Compromise? The market offers devices that combine an air purifier and a dehumidifier. While they save space, they often lack the power needed for larger areas, making them suitable only for very small rooms. When it comes to the Air Purifiers on these units, they fall well short of being effective for anything beyond a medium sized bedroom. Because of this, we recommend purchasing standalone units of each. If you're interested in learning more, we've written an article on these combo units. Health Impacts of Mould Mould is not just an aesthetic issue or a homeowner's nuisance; it's a health hazard, particularly for those with allergies or respiratory conditions. Understanding the full scope of its impact can help prioritise why air quality management is essential. The Allergic Reactions to Mould Exposure to mould can trigger a variety of symptoms in sensitive individuals. These may include sneezing, runny or blocked nose, red eyes, and skin rash. For those with mould allergies, these symptoms can be more severe, leading to persistent allergic reactions that can significantly affect quality of life. Mould's Effect on Asthma and Other Respiratory Issues For asthmatics, mould can be particularly harmful. It has the potential to increase the frequency and severity of asthma attacks. Even those without pre-existing conditions may experience respiratory issues in mould-infested environments, such as coughing, wheezing, or shortness of breath. Chronic exposure can even lead to the development of respiratory illnesses in otherwise healthy individuals. Our Powerful, Affordable Solutions Meet Our HEPA Heroes Our air purifiers are equipped with HEPA filters and are designed to be powerful enough for New Zealand's varied home sizes, yet affordable to fit within your budget. With our units, you can ensure that the air in your home stays clean and clear of mould allergens.

When setting up a nursery for your precious little one, there's a checklist of essentials most parents are aware of - a crib, changing table, soft lighting, and comforting decor. But have you considered the air quality in the nursery? You might wonder, "Is an air purifier a good addition to my nursery?" The answer is a resounding yes! An air purifier can be a nursery necessity, safeguarding your child's health by filtering out harmful pollutants and ensuring a peaceful sleep. Key Points Summary: Childhood Asthma in NZ: Asthma is prevalent among children in New Zealand; an air purifier can help by removing airborne irritants. Negative Ion Concerns: Avoid air purifiers releasing negative ions as they can produce ozone, harmful to tiny lungs, especially concerning given some are marketed for nursery use in NZ. Combatting Odours and Allergens: Air purifiers tackle odours, pet dander, and outdoor pollution that seeps indoors, ensuring a fresh and clean nursery environment. Virus and Bacteria Reduction: Create a healthier space by reducing the presence of viruses and bacteria, crucial in a child's early years for better immunity. Noise and Light Considerations: Choose a quiet air purifier with minimal light emissions to maintain a serene, sleep-conducive nursery ambiance. Affordable, Effective Options: Our range of air purifiers offers high CADR (Clean Air Delivery Rate) and low noise levels without breaking the bank, tailored for New Zealand homes. Why An Air Purifier is Essential The early stages of life are certainly special. But this phase also brings vulnerability, especially to elements in the environment. The air that we breathe can either help us become strong and healthy, or harm us. Here’s a deeper look into why investing in an air purifier is an important consideration for your nursery: The Unseen Threats: Viruses and Bacteria While sickness is inevitable at young ages, there are ways to mitigate this risk. Air purifiers work to reduce the presence of viruses and bacteria in the air.  The Surprising Risk of Outdoor Pollution New Zealand's picturesque landscapes can be deceiving when it comes to air quality. Construction, vehicle emissions, and fireplaces contribute to outdoor pollution, including the dangerous PM2.5 pollutants, which can infiltrate your home, posing a risk to your little one. Pet Dander and Other Allergens Many families couldn't be without their furry companions, but pets can introduce dander and other allergens into the air. An air purifier can significantly mitigate these allergens, ensuring a fresher environment for your child. Take a look at our article to learn more about how an air purifier can help with pets. The Impact of Air Quality on Children Children, with their still-developing organs and faster breathing rates, are more susceptible to the adverse effects of poor air quality. This article by Smart Air sheds light on how air pollution can affect children even before birth, linking exposure to certain pollutants with birth defects. Air pollution doesn't spare the toddlers and young children either. It has been associated with neurodevelopmental disorders, childhood obesity, reduced lung growth, acute lower respiratory infections (ALRI) like pneumonia, asthma, and even childhood cancers. A staggering fact is that air pollution accounts for 1 in 10 deaths in children under five years old globally. Given these alarming facts, the case for a quality air purifier in your nursery becomes a compelling one. An air purifier equipped with a HEPA filter and a carbon filter can significantly reduce the exposure of your child to these harmful pollutants, providing a safer environment for them to grow and thrive. Choosing the Right Air Purifier Not all air purifiers are created equal, especially when it comes to safeguarding the health of our little ones. We've got an in depth guide here, but here are some crucial factors to consider: No Negative Ions It’s alarming to find a range of air purifiers in New Zealand marketed for use in nurseries that release negative ions. While they might sound harmless or even beneficial, these ions can produce ozone—a gas that’s harmful to the lungs, particularly the still-developing lungs of a child. In New Zealand the negative ion generation 'feature' is often marketed with different names including ionisers, plasma generators and more. HEPA Filters Are Your Friend HEPA filters HEPA filters are the gold standard in air purification, capturing over 99% of 0.3 microns sized particles - the hardest to capture. Ensure that the air purifier you choose has a genuine HEPA filter, and avoid products with "HEPA-like" filters, which are less effective. Consider the Noise and Lights You’ll want an air purifier that operates quietly to ensure your baby can sleep soundly through the night. Similarly, many air purifiers come with bright lights which could disturb your child's sleep. Look for models that operate under 30dB on low and allow you to turn off the lights (or like ours which have no lights!). Price and Performance Investing in a quality air purifier pays off in the long run. Make sure to look at the Clean Air Delivery Rate (CADR) when comparing air purifiers, and not the room sizes recommended by manufacturers as they can be misleading! Our Selection for Your Peace of Mind We’ve curated a range of air purifiers tailored for New Zealand homes, ensuring safety and effectiveness. Our selection of Smart Air purifiers avoids any models that release negative ions, operates at low noise levels and most importantly is affordable! For use in a nursery, we recommend either: Smart Air - The Sqair, or Smart Air - SA600 Wrapping Up Investing in a good air purifier is investing in your child’s health. As parents, we can’t control the outdoor air quality, but we certainly have a say in the air our little ones breathe indoors. Take a step towards creating a safer, cleaner environment for your baby, and breathe easy knowing you’ve made a sensible choice.

Waking up to a stuffy nose, feeling congested, or experiencing exacerbated asthma symptoms can be early signs that the air quality in your bedroom needs improvement. Air purifiers are a proven way to enhance the air we breathe as we snooze. However, while on the search for cleaner air, the last thing anyone wants is a noisy machine buzzing through the night. This piece dives into the essential factors that contribute to making an air purifier both effective in purifying the air and quiet enough to ensure a peaceful night's sleep. Top considerations for your bedroom air purifier: Noise Concerns: A loud air purifier can be a deal-breaker for restful sleep. It's important to find a balance between effective air purification (CADR values) and low noise levels, especially on lower speed settings. Transparency in Performance Metrics: Many manufacturers may not provide clear CADR values at quieter settings or may overestimate the recommended room sizes. Transparency in noise level and CADR metrics is key to make an informed choice. What Does 'Quiet' Really Mean? For undisturbed sleep, experts recommend air purifiers with noise levels below 30dB. Some models, like The Sqair (23dB), SA600 (24dB), and Blast (29dB), fall within this quiet spectrum. Don’t Let the Lights Disturb You: The display lights on air purifiers can be disturbing in a dark room. Opt for simple models with no lights or displays which can switch off to maintain a dark, sleep-conducive environment. The Balancing Act: Noise Levels and Air Purification Efficiency The Noise Factor The tranquility of your bedroom is paramount. While some air purifiers may sound like mini-tornadoes on their max settings, finding a quieter option that doesn't compromise on air purification is key. CADR Values at Quieter Settings Lower settings often equate to quieter operation but may also mean decreased CADR (Clean Air Delivery Rate). It's a tad challenging since many manufacturers often skirt around providing CADR values at these quieter settings. Manufacturers can also be a bit too optimistic with their recommended room sizes. In reality, on lower speed settings, a few of these units might just about manage the air in your wardrobe! Transparency in Performance Metrics We believe in transparency and provide the noise level and CADR of all our products to help you make an informed choice: Model Speed CADR Space cleaned in 20mins Noise The Sqair High 315m³ 42m² 52dB Medium 180m³ 24m² 43dB Low 65m³ 9m² 23dB SA600 High 500m³ 67m² 53dB Medium 260m³ 35m² 39dB Low 135m³ 18m² 24dB Blast Mini High 740m³ 99m² 49dB Medium 450m³ 60m² 43dB Low 340m³ 45m² 36dB Blast High 950m³ 127m² 43dB Medium 680m³ 91m² 37dB Low 450m³ 60m² 29dB  So, How Quiet is 'Quiet'? For peaceful sleep, experts generally recommend noise levels below 30dB. To give you a helping hand: Model Noise level (low) The Sqair 23dB SA600 24dB Blast 29dB However, if you’re a fan of white noise (pun intended) and find it soothing, then you can afford to crank your air purifier up a notch without compromising on sleep quality. Lights Out for Better Sleep One often overlooked aspect of air purifiers in bedrooms is their displays. While many air purifiers come with display lights that can disrupt your sleep, our models are designed with simplicity and effectiveness in mind, devoid of any light-up displays. This ensures nothing comes between you and a peaceful night's sleep, maintaining a dark, serene environment perfect for rest. Wrapping it Up Selecting the right air purifier for your bedroom might take a bit of research, but the rewards — in the form of undisturbed, rejuvenating sleep — are well worth the effort. Ensure you consider noise levels, CADR values at those levels, and the option to have a light-free night. Here’s to breathing easy and sleeping even easier!

Springtime in New Zealand brings new growth, vibrant blossoms and finally a warm change to the chilly air. Unfortunately with this change, it’s also the season of sneezes, itchy eyes, and an endless supply of tissues. If you’ve tried everything from allergy meds to dodging outdoor activities during high pollen days, you might be wondering, can an air purifier help with allergies? Absolutely! Moreover, you might also be curious, what do the best air purifiers for allergy relief have in common? From HEPA filters to high CADR ratings, let’s unravel the common features of top-notch air purifiers that could be your allies in battling allergies. What's Ahead: Understanding Allergens: What causes them and their impact. HEPA Filters: Your frontline defense against airborne allergens. CADR (Clean Air Delivery Rate): Uncovering why this rating matters for effective allergy relief. Top Picks for Allergy Relief: Some top picks well-suited for New Zealand homes. Maintaining Your Air Purifier: Ensuring your device remains an allergy-fighting powerhouse. Extra Tips for Allergy Relief: Steps beyond air purification to keep those allergens at bay. Avoiding Harmful Features: Knowing what to steer clear of when choosing your air purifier. Spring Allergens Spring in NZ brings about allergens for many of us. Understanding common indoor allergens and how they affect your health is the first step toward better allergy management. Common Indoor Allergens Pet dander, pollen, dust mites, and mould spores are among the usual suspects that trigger indoor allergies. Outdoor allergens like pollen, grass etc will often make their way indoors causing allergic reactions. How Allergens Affect Your Health These airborne particles can cause symptoms ranging from sneezing and itchy eyes to more severe respiratory issues, particularly for asthma sufferers. HEPA Filters: Your Defense Against Airborne Allergens HEPA (High Efficiency Particulate Air) filters are proven champions in trapping airborne allergens. How HEPA Filters Trap Allergens HEPA filters are the gold standard for filtering particles. With their tight weave of random fibers, they can capture particles smaller than 0.01 microns. With pollen sizes starting at about 10 microns in diameter, HEPA filters effectively capture these sneeze inducing particles. Different Types of HEPA Filters Though there are variations, the efficacy against allergies across HEPA filter types is quite consistent. An H11 rated filter capturing 95% of particles may sound vastly inferior to an H14 filter with a > 99.995 capture rate. However this is based on the trickiest to capture 0.3 micron sized particle. With pollen and common allergens being much larger in size, what matters more is the CADR of the air purifier. The Significance of CADR (Clean Air Delivery Rate) Understanding CADR helps you choose an air purifier capable of handling the size of your space. CADR Explained A higher CADR indicates a more efficient air purifier that can clean larger volumes of air at a faster rate. This means allergens will be removed from the room faster. Debunking Misleading Room Size Recommendations We've found many manufacturers in New Zealand using very exaggerated room size claims. To avoid this, compare models based on the industry standard CADR for a more accurate representation of their capability. Top Picks for Allergy Relief Finding the right air purifier for your space can significantly improve your allergy symptoms. Choosing an air purifier model While researching you're bound to encounter a multitude of air purifiers and review sites claiming theirs is the "best for allergies,".

There is no benefit for allergy sufferers here, just an additional cost. Final Thoughts Investing in an air purifier can be a transformative experience for anyone who suffers from allergies. Remember, the key lies in choosing a device with a HEPA filter and high CADR, while avoiding potentially harmful features. Our air purifier collection makes this choice easier than ever, offering affordability without compromising performance.

Air quality is an essential but often overlooked aspect of our well-being. In New Zealand, many remain unaware of how winter weather can profoundly affect the air we breathe. The Unseen Winter Culprit Winter air pollution in New Zealand is mainly shaped by weather patterns and heating choices. In the colder regions, while less common than previous years, we still see fireplaces being used for warmth. These emit particulate matter; tiny harmful particles into the air we breathe. Even though recently there have been tightened standards as far as emissions from these, they've focused on reducing the larger PM10 particles. The levels of PM2.5 seen in the air however, frequently exceed WHO recommendations. Inversion Layers: A Winter Phenomenon The New Zealand climate significantly influences air quality. In winter, many areas experience cold, still nights. These conditions, along with geographical features like mountains, create 'inversion layers'. This traps cold air and pollutants close to the ground, boosting harmful particle levels. We commonly see these occur in valleys and parts of Canterbury, Otago, Southland and Marlborough. Inversion layers occur when a layer of warm air sits on top of cooler air. This is the reverse of what we normally see where air gets cooler at higher elevations. This "lid" traps pollutants, contributing to higher PM10 and PM2.5 concentrations. PM10 and PM2.5 are particulate matter, or tiny particles in the air. PM10 particles are less than 10 micrometres in diameter, and PM2.5 are smaller, less than 2.5 micrometres. The tiny PM2.5 particles are concerning, as they penetrate deep into the lungs and bloodstream. Health Implications of Poor Air Quality Air quality influences our health. Both PM10 and PM2.5 pose health risks. The smaller PM2.5 particles, which can infiltrate our respiratory system, exacerbate conditions like asthma and COPD and can contribute to heart disease and lung cancer development over time. The World Health Organization states PM2.5 exposure can lead to respiratory and cardiovascular issues, hospital admissions, and mortality from cardiovascular and respiratory diseases and lung cancer. Understanding air quality's link to health is vital, especially for those in colder New Zealand regions, where winter pollution can be harmful. Pollution levels in these areas can reach unhealthy and even very unhealthy levels at times. Measures to Improve Air Quality As we gear up against winter cold, we can also protect ourselves from air pollution. Monitor the Air Quality Understanding the air quality in your area is important. In many countries checking the air quality is as common a task as checking the weather. Monitoring can help us make informed decisions about when to go outside and for how long during poor air quality periods. LAWA (Land Air Water Aotearoa) has a great air quality dashboard which can tell you more about the trends in your area. For live air quality monitoring check out the aqicn website. It can also help to monitor your indoor air, as outdoor pollutants can seep into your home. Personally, I found in my Christchurch home that during cold winter nights the air inside my home would often reach unhealthy levels due to the pollution. Want to check if the same happens to you? We have affordable and high accuracy air quality monitors available on our website. Air Purifiers and Filters Quality air purifiers can remove harmful particulate matter from your home's air. Opt for purifiers with HEPA filters to remove PM2.5 particles. We provide a range of proven, affordable and effective air purifiers from Smart Air. Clean Heating Cleaner heating options can improve air quality. If possible, consider shifting from wood burners to cleaner heat pump options. Wrapping up Awareness is the first step in enhancing our winter air quality. The more we understand, the better we can protect our health and communities. Stay informed, take action, and breathe easier this winter.

Considering the hours we spend at work, maintaining a clean and healthy office environment is a necessity, not a luxury.  One might wonder, can an air purifier make a significant difference in the office? The answer is a resounding yes! Introducing the best office air purifier into your workspace can be a game-changer in enhancing the office air quality, thereby reducing the spread of illnesses like COVID-19 and flu, which is key in ensuring the productivity and well-being of the staff, especially those with allergies or respiratory issues such as asthma. Key Considerations for getting an Office Air Purifier: Preventing Illness: Air purifiers can significantly reduce the spread of airborne diseases like COVID-19, thereby keeping your staff healthier.

Suitability: Ensure the air purifier’s CADR is suitable for your office size to get the most out of your investment. The Importance of Clean Air in Offices When we think of air pollution, it's easy to picture smog and outdoor emissions. However, the reality is, indoor air pollution often surpasses what we encounter outdoors, particularly in office environments. The very places we spend a large chunk of our days may harbor a cocktail of airborne pollutants, potentially harming our health and dampening our productivity. Mechanical ventilation systems in commercial setups are not always up to the task. Sometimes, they could be circulating, rather than eliminating, pollutants like dust, mould spores, volatile organic compounds (VOCs), and allergens. This circulatory action of pollutants could lead to what is termed 'sick building syndrome,' where occupants experience an array of symptoms like headaches, fatigue, and difficulty concentrating. The impacts can be broad-ranging, affecting not just the health but also the morale and productivity of employees. Research underpins the importance of good air quality on cognitive function and overall productivity. This study highlighted that improved ventilation in office spaces could lead to an 8% boost in employee performance. That's a significant uptick, underscoring the important role of clean air in enhancing work efficiency and creating a healthy environment for staff. The drive towards ensuring clean air in offices isn't just a matter of adhering to health standards; it's about creating a space where employees can thrive, innovate and contribute to their full potential. Hence, aiming for better air quality in New Zealand offices isn't a luxury; it's a necessity which both helps workers and the business.  Choosing the Best Office Air Purifier: Factors to Consider Noise Levels When it comes to offices, a quiet environment is normally best for productivity. It's advisable to opt for air purifiers with noise levels around or below 50dB to ensure that normal communication and concentration aren’t hampered. Budgeting and Value An air purifier is an investment in health. While considering the cost, it's wise to look beyond the initial price. Evaluate the long-term expenses like filter replacement costs, availability, and lifespan. Our air purifiers boast long filter lifespans due to their large surface area, offering you better value for your money. Clean Air Delivery Rate (CADR) CADR is the key factor in determining the effectiveness of an air purifier. While it seems simple enough to look at the recommended room sizes provided by manufacturers, unfortunately these can often be misleading. The best way is to compare the CADR values, which provide a more accurate indication of the air purifier's capability.

Breathing clean air is essential to maintaining our health, and the rising concern of air pollution has made air purifiers a common household item. However, the wide array of models and features can make choosing the right one quite challenging. This article breaks down the crucial features you should look for in an air purifier, such as HEPA filters, activated carbon filters, high Clean Air Delivery Rate (CADR), low noise, and durability. We'll also debunk some gimmicks that are often marketed but may not add value or may even be harmful, like negative ion generators, UV lights, and auto sensors. The Gold Standard: HEPA Filters HEPA filters are the pillar of effective air purification. They can trap microscopic particles smaller than 0.3 microns, including dust, pollen, and pet dander, offering relief for allergy sufferers and those with respiratory issues. It's essential to select an air purifier with a genuine HEPA filter. Neutralise Odours: Activated Carbon Filters   In addition to a HEPA filter, an activated carbon filter can enhance an air purifier's performance. This type of filter excels at trapping and neutralising odors and chemicals, providing a more comprehensive air purification solution when combined with a HEPA filter. Efficiency Matters: High CADR CADR, or Clean Air Delivery Rate, measures an air purifier's efficiency in cleaning air. A high CADR rating indicates an air purifier can filter a large volume of air per hour, which is a key factor to consider when choosing an air purifier. Quiet Operation: Low Noise     The noise level of an air purifier can affect your comfort, especially in quiet spaces like bedrooms. Choose a model with a low noise level, ideally under 55 decibels. Many purifiers offer a "sleep mode" for quieter operation during rest or quiet periods. Durability When investing in an air purifier, durability matters. For commercial-grade units, metal construction is preferable for its longevity. Our Blast and Blast Mini air purifiers are excellent examples of durable, high-quality air purifiers. Features to Be Wary Of While some features enhance an air purifier's functionality, others can be unhelpful or even harmful. Here are some to avoid: Negative Ion Generators/Ionisers These devices produce negative ions that attach to airborne particles, causing them to fall onto surfaces. Do you want these falling on your bed? Unless you're regularly cleaning every surface, we think it's much better if these particles end up in the HEPA filter of your air purifier! The reason these are included, is because it makes the purifier perform better in CADR tests. Particles falling to the ground still counts for these tests. So, if you don't use the ioniser, the CADR will actually be less than what's marketed. Negative ion generators can also produce harmful ozone as a byproduct. Especially concerning for younger ones, elderly or if you suffer from respiratory problems. We've seen these marketed for nurseries of newborn babies in New Zealand, which we consider extremely irresponsible and dangerous. None of our air purifiers include negative ion generators for this reason. UV Lights UV lights are marketed as a way to kill bacteria and viruses in the air, but they can be ineffective against many common allergens and pollutants. While UV lights can kill bacteria and viruses, the main issue is they require time to kill them. If air is quickly passing through the air purifier, the UV light won't have enough time to do its work. Remember as well HEPA filters can normally capture upwards of 99% of these anyway. Auto Sensors Auto sensors, while seemingly convenient, can be wildly inaccurate and may not represent the overall air quality of your space. Instead of relying on these, consider our QP Air Quality Monitors for a precise read on your indoor air quality. An Optional Extra: WiFi     WiFi-enabled air purifiers may seem appealing for those who enjoy remote control or smart home integrations. However, this feature may not be necessary for everyone and can add to the cost. Our range of air purifiers keep things simple and affordable, without WiFi connectivity. However, for those who wish to have this feature, a WiFi-enabled smart plug can be purchased separately at any electronics shop for a reasonable price. Wrapping Up When selecting an air purifier, look beyond the marketing hype and focus on the features that genuinely improve air quality and add value. Always remember that clean, breathable air is the ultimate goal. By making a wise choice, you can ensure a healthier and more comfortable living environment in New Zealand. Choosing the right air purifier can be a daunting task, but we hope this guide has made the process simpler. For more detailed information, don’t hesitate to check our comprehensive guide for Choosing an Air Purifier. And remember, we're here to help you breathe easier.
